HOW OLD IS A PERSON WHO IS A MILLION SECONDS OLD. AND A BILLION SECONDS OLD

Google: "X units1 in X units2" converts X in units1 to X in units2; example:

1,000,000 seconds in years

returns:

1 000 000 seconds = 0.0316887646 years

That's a bit strange, so convert to smaller units:

0.0316887646 years = 1.65343915 weeks

1.65343915 weeks = 11.5740741 days
